🕹️ raichi-engine

raichi-engine is a lightweight 2D game engine written in TypeScript, built from scratch for educational and experimental purposes.
Inspired by classic game engines like Cocos and Love2D, with a strong focus on clarity, modularity, and full control.

🚀 Features

• Custom game loop with deltaTime handling
• Component-based architecture
• Scene management system
• Keyboard input handler
• Simple animator/tweening system
• WebSocket-based live reload (no Vite/Webpack)
• Express dev server + TypeScript build system
• Clean structure for separation of engine and game
